The father god of Vana'diel, seeder of the beastmen races and all strife, he gave sin to each of the five races of light. To the humans, he gave apathy. to the Elvaan he gave arrogance, to the Tarutaru he gave cowardice, to the Galka he gave rage, and to the Mithra he gave envy. Promathia appears as a faceless, human with four wings. His body fluctuates through the color specturm, each area of his body independant of the rest.

In civilized lands, temples to Promathia are nearly unheard of, and, those that do exist, are always hidden. Among the savage lands of the beastmen, each tribe is likely to have at least a small shrine to the God of Twilight.
